Help text

If you say Y here you will be able to repair metadata on a mounted XFS filesystem. This feature is intended to reduce filesystem downtime by fixing minor problems before they cause the filesystem to go down. However, it requires that the filesystem be formatted with secondary metadata, such as reverse mappings and inode parent pointers.

This feature is considered EXPERIMENTAL. Use with caution!

See the xfs_scrub man page in section 8 for additional information.

If unsure, say N.
